rails E and similar webs of the rails G fit neatly into these slottedarms and the webs are attached to the arms by means of the siding atHegewisch, Chicago, in the county bolts 5 and nuts 6, as usual. Thebases of 60 5 of Cook and State of Illinois, have invented theCOIlIleCtlg mils E E' E2 E3, and the certain new and useful Improvementsin bases Of the rails F and G where they are Railway-Crossings, of whichthe 'following coupled with the arms of the base plate, are is aspecification. omitted from these rail sections, but these The presentinvention relates to improvebases are Supplied by the cruciform cast- 65i ments in railway crossings, and is designed lhg's as Shown. y

,j Each of the four joints is built upon a respectively so that, asclearly seen 1n Fig 105 base plate of cruciform shape comprising 6, theguard m11 8 may sWlIlg t0 the right the four arms 1, 2, 3, and 4C. Thesearms are without interference from the rail 7, and each slotted as at 4and the usual rail heads the rail 7 may swing to the left Without areomitted from the arms, but the heads of interference from the rail S. Toreinforce the sections F, Gr, E, E E2 and E3 are suband brace the jointbetween these crossed 110 stituted therefor, while the webs E4 of therails I provide them with angular lugs as connecting sections and theWebs F of the 7a and 8n respectively, and the outer face of these'llugs` is struck froma line With the` hinge bolts 10 as a center. Each ofthese lugs is alined with the tracky that it intersects, and theconnection rails or sections E E E2 and E3 have their ends 17 rounded atthe underside of their heads so that these lugs may turn doWn under theends. At 7b and 8b the lugs 7a and 8@L are slotted so that they may folddown past the ends of the Webs E4, as indicated in Figs. 4 and 5, andthisarrangement of parts further adds to the stability of the devices.

In operation, assuming a car to be passing over the crossing from leftto right in'Fig. 3, the lianges of the Wheels Will engage the guardrails 7, 7 and turn them both in'- Wardly and hold the rails in thisposition until the Wheels have passed through the joint, when the railsare turned back to normal position by the springs 18. The second pair ofrails 7 is noW encountered by the Wheels and they are also turnedinwardly, and after passage of the Wheels, are returned by their springs13. It Will be noted that the track from left to right is continuous andsmooth and the Wheels travel over a continuous surface, as the gaps areclosed and filled on the track over Which the Wheels are to pass. Inthis manner the objectionable features of noise and Wear are avoided inthe crossing of cars, and the guard rails after being opened by the carWheels and held so until the Wheels pass, are automatically returned tonormal closed position. All parts 'Copies ot this patent may beobtainedlor ofH the rail sections are closeitting, as seen in Figs. 2, 4and 5, and the tops of the rails or rail heads form' a continuous andsmooth surface for the Wheels to travel over.

What I claim is l. The combination in a rail crossing With four cornerbase plates and rail sections connecting them, of a pair of crossedguard rails hinged at the sides of the crossing arranged in pairsparallel With the intersecting rails and adapted to be turned down ontheir hinges, and means for holding the guard rails in normal uprightposition.

2. The combination with a cruciform shape base plate, of a pair ofnotched and crossed guard rails each respectively hinged to the baseplate at the sides of the corner and adapted to be turned down flat,bolts passed through perforations in the rails and base plate, andsprings held on said bolts to return the guard rails to normal uprightposition.

3. The combination with a cruciform base plate of a pair of notched andcrossed guard rails separately hinged to the base plate and each formedWith a projecting lug formed with a circular 'face adapted to co-actWith the rail that the guard rail intersects, and means for holding theguard rails in normal position.

In testimony whereof I aiiX my signature.

JOHN C. ENGSTRAND.
